my mother and i are going to install kill switches on 2 cars(one of my cars, one of her cars).
its the kind of kill switch that has a large removable red key.
mostly so the battery of both cars don't die out when they aren't being driven for lengths of time(especially during the cold).

I'm not sure on the exact year, but one needs to be installed on a mustang of the 1979–1993 body style.
the main issue i see with this car is that the car needs a current running through it for the radio, clock, alternator(i assume the alternator needs a current).
the second car is my 57 Chevy no working clock or radio in it currently so a constant current is not needed for it atm.

i have read about people wiring a self-resetting circuit breaker(10-15 amp) to bridge between the kill switch to allow a current to still keep the radio and clocks set.
is this a good idea? does anyone have more information about wiring a self-resetting circuit breaker between a Kill switch, what i would need, where i could get parts?

sitting in the garage the mustang radio presets/clock/maybe the cpu only draw "milliamps" (1,000th's of a amp) to operate....
ex: a wrist watch works for 2 years (?) with just that tiny batt inside....

57' should be 0.000amps just sitting (but any wiring harness can have minor voltage bleed,,,very common in old harnesses and switches)

Actually, you can now buy the disconnects that go right on the battery terminal with a small fused bypass wire (like 3 amps or so) to retain memory and clock functions when disconnected. The small fuse will burn out if someone tries to start the car.

If something, a short circuit, trips a breaker, how could it possibly reset itself without;
1. Instantly tripping again... and again and again and again... unremittingly towards perpetuity.
2 Sending out a crew of little green men to repair the short so the self-resetting breaker doesn't #1 above.

Circiut breakers can be manually reset by the pilot ....or driver, as it were. but the F-ing things don't reset themsleves; ergo such a device would be defeating the purpose of said, such a device.

Want to learn something about circuit breakers? Study the purpose of the Master Caution annunciator in aircraft.

You can also buy a solar powered battery tender that trickles to the battery that plugs into the cig. lighter or acc. power socket. You set the panel on the dash but, it only works for cars parked outside.

OLD ROTOR FLAP, There is a self resetting circuit breaker that comes in International semi trucks that break when they get hot and will reset when they cool off. I don't think it is the type that will work for what he want's
but I encountered them after my running lights kept going out while driving down the road and after pulling over and sitting for a few minutes and shutting the lights off they would come back on after the breaker would cool off. As you stated they would just keep resetting over and over again. A new breaker (plug in type) and removing the cover from the breaker circuit board behind the glove box helped keep it cooler and I had no more problem.

Old Rotor Flap, the most common OEM use of the type circuit breakers being discussed, ("self resetting"),is for power seats and/or power windows in Ford and GM cars,
Many Ford and GM headlight switches also have them incorporated into the switch unit.
